Our Verdict
LG UA77
TCL Q77K
The TCL Q77K is better than the LG UA77. The TCL has a much higher native contrast ratio, resulting in deeper blacks in dark scenes. The TCL is also much better for gaming thanks to its impressive array of gaming features, including HDMI 2.1 bandwidth, a wide VRR range to reduce tearing, and a very high maximum refresh rate.
